JOHN S. BARNES, OF ANN ARBOR, I IEGI-IIGAN, ASSIGNOR TO NIB/E PRODUCTS CORPO- RATION, OE ANN ARBOR, MICHIGAN, A. CORPORATION OF IiIICI-IIGANQ PROCESS OF VTEAVING WIRE FABRICS.

Application filed December 14, 1921. Serial No. 522,212.

To all whom it may concern:

Be it known that 1, JOHN S. BARNES, a citizen of the United States, residin at Ann Arbor, county of Washtenaw, btate of Michigan, have invented a certain new and useful Improvement in Processes of lVeaving ire Fabrics, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a process of wea ing wire fabric for the manufacture of partitions, window-guards, crates, tops for commercial vehicles, etc.

In constructing the foregoing or like articles of wire it has been customary to employ a channel iron frame or the like, to enclose the marginal edge of the wire fabric in order that a rigid structure may be obtained. By my process however a rigidly constructed fabric may be initially formed around which it is unnecessary to mount an enclosing frame thereby materially reducing the cost of manufacture.

In carrying out my invention a continuous wire is used to form the warp,which is interlaced by a plurality of woof strands secured at each end to the marginal return bends of the warp.

A further object of the invention is the method of interlacing the woof members whereby they may be readily inserted between the parallel return bends of the warp member in building up a fabric of desired size and construction.

In the drawings accompanying this specification:

Figure l. is a diagrammatic perspective view showing an adjustable supporting frame with a continuous strand of wire forming the warp laced upon the creme.- lated bars of the frame that the return bends of the warp may be supported on the same plane and in fixed relation to each other to receive the interlacing woof strands.

Figure 2 is a diagrammatic view of the warp with the two outer woof strands 1n place and an interlacing device for inserting other woof strands in position.

Figure 3 is a similar diagrammatic view showing the next woof strand in positionindicated on the right hand side of the fabric.

Figure 4 is a like view with the next succeeding woof strand in position indicated on the left hand side of the fabric ;the interlacing device being in position to insert the central or last woof strand required to produce the finished fabric.

It will be understood that while the diagrammatic views 2, 3 and t fail to show the supporting frame with the warp laced there on, the woof strands are interlaced through the return bends of the warp while the latter s mounted upon said supporting frame 1t was not however deemed necessary to show 1 the supporting frame in each of the latter views. When the fabric has been completely finished by the insertion of the required number of woof strands the ends of the latter are then looped around the marginal bends of the warp strand, whereupon the completed fabric may be released from the supporting frame. in order that a better understanding of the process may be had thesupporting frame is briefly described as follows :-To a suitable bench A is rigidly bolted a crenelated angle iron B, mounted upon a member C to raise it above the top of the bench. Directly opposite and in spaced relation thereto is an adjustable crenelated slidable member D, upon a plate E, provided with projecting pins F extending through slots in the flange of the member D. G, G, G, denote bell crank levers pivoted to the plate E and respectively connected by links I, I, I, with the member D. J, is a bar connecting the several bell crank levers with a lever K pivoted to the bench and provided with a dog K to engage the teeth of a suitable segment L, whereby the member D may be rigidly held when adjusted. M, denotes a wire reel supported in a suitable manner from which the warp wire is guided to the upstanding inclined crenelated walls of the angle irons. In lacing the warp wire N upon the supporting frame the end of the wire is first secured in any suitable manner, the wire is then guided back and forth around the upstanding crenelated walls B, D" of the angle irons until the required length of fabric is provided as clearly indicated in the drawing. The woof wires P I claim is:

1. The process of forming wire fabric consisting in securing one end of a continuous strand in a supporting frame and lacing the same to form return bends, interlacing woof strands across the return bends alternately and securing each end of each woof strand to the marginal return bend of the. fabric.

'2. The process of forming wire fabric consisting in securing one end of a continuous strand in a supporting frame and lacing the same to form-return bends, interlacing a plurality or" woof strands across the return bends alternatel from the sides of the first mentioned laced strand toward the center, and securing the ends of each woof strand to the marginal return bend of the fabric.

3. An article of manufacture comprising a -laced wire fabric forming return bends in spaced relation to each other, woof strands interlaced alternately with the said return bends and having each end secured to each of the marginal return bends of the fabric.

in article of manufacture comprising laced wire warp strands forming return bends in spaced relation to each other and in substantially the same plane, interlaced woof strands crossing the warp strands alternately and secured to the marginal return bends of the fabric by looping the same around the marginal strands.

5. An article of manufacture comprising a laced wire fabric forming return bends in spaced relation to each other and baring woof strands interlaced across the return bends alternately from the sides of the first mentioned laced strand toward the center,

the ends of each Woof strand being secured to reach of the marginal return bends of the fabric.

In testimony whereof, 1 sign this specification in the presence of two witnesses.
